The bounty hunter turns out to be a friend of Nolan's and former comrade in arms, named Eddie (Rob Stewart).

Tommy (Dewshane Williams) identifies the Castithan as Pol Madis (Daniel Kash), the person who designs many weapons for wars.

While Yewll (Trenna Keating) examines Madis, he asks her if people of Defiance know about her involvement in the Pale Wars.

Datak, not having a second choice, drives him out of Defiance, but they are stopped by Nolan, Irisa (Stephanie Leonidas), Tommy and Eddie.

Meanwhile, Quentin (Justin Rain) studies the book and the artifacts his brother left behind to understand what Luke was trying to do.

"One infuriating moment aside, I found a lot to like about “Brothers In Arms.” A television show isn't just about its grand, overall story.

Defiance is doing well enough at that, especially early in a science fiction drama's run, so I'm willing to forgive brief dalliances with shitty mythology.
